Specification forming part of Letters Patent N o. 180,917, dated August 8, 1876 application filed June 12, 1876.

To all whom tt may concern:

Be it known that I, CHARLES PETTLT, of Erieville, in the county of Madison and State of New ,York, have invented a new sind Improved Combined Stove- Pipe Thimble and Register, of which the following is a specificaprovided with openings to allow the air to pass for Ventilating and for heating, and one is provided with Va register.

Figure 1 is a sectional elevation of my improved combined thimble and register. Fig. 2 is a plan of the ltop plate, and Fig. 3 is a plan ot' the bottom plate.

A is the large tube extending through the ceiling B and oor B', and supported by the register-plate C below, which is attached to the ceiling, while at the top it is covered by the plate D, having a ange,`F, fitting in the hole in the door and over the top of tube A. Said plate D also has a lange, Gr, and holes E. The flange is for the connection of tube H, which incloses a space, J, between it and the thimble I, in which the stove-pipe passes, said space to be filled with non-conducting material, it' preferred. Tubes H and I are made in two parts, which tit together by an together with it.

extensible joint, to lit floors and ceilings of different distances apart. They rest on the bttom plate O, and tit around a flange, ol, which keeps them in place, and may be cast The inner tube Iconnects at the top with the tube H by the horizontal flange c, (shown dotted in Fig. 2,) said liange being provided with large openings to let the heat out through a register, L, fitted over the space J, to close it when desired. Inside ot' the plate C, which has openings for the air to pass through, is a register, K, to regulate the passage otl the air.

P is a cover for the stovepipe hole when the pipe is taken out in summer, and N is a plug for stopping the pipe-hole at the lower end. It is inserted from below, and is secured to lugs f by a kind of bayonet-fastening. Plate D may also have a ring to cover holes E, it' desired.

'1 Having thus described my invention, what `I claim as new, and desire to secure by Letters Patent, is-

Ihe combination ot' tubes A, H, and I and plates C D, when arranged with the air-space J closed at the bottom, and either open or closed at the top, and with passages in the plates to the s'pace between plates A H, with a register, K, in the lower plate G, for opening and closing them, substantially as specifled.
